From Continuous Time to DiscreteTime

Learn how to acquire digital samples from continuous-time signals.

We'll cover the following

Most signals in real life, e.g., heartbeat, brain waves, sound, music, wireless communication waveforms, etc., are continuous-time signals. To process such a signal using DSP techniques, it must be converted into a sequence of numbers. This can be done through the process of periodic sampling with the help of a device known as an analog-to-digital converter (ADC).
